Dixon Valve gc620 Dry Pressure Gauge 0-160 Psi

Product Description

The DIXON VALVE gc620 is a dry pressure gauge designed for accurate pressure measurement in fluid and gas systems. Unlike liquid-filled gauges, the dry configuration suits environments where ambient vibration and pulsation are minimal. The gauge features a 1/8 inch back mount connection and a 0-160 psi range, making it suitable for monitoring low-to-moderate pressure circuits. Licensed plumbers, HVAC technicians, and pipefitters install this type of instrument to verify system pressures during commissioning, service, and routine inspection. The dry dial face delivers a clear reading without the potential for fill-fluid contamination.

This gauge is well suited for residential and light commercial plumbing, HVAC, and compressed air applications where a compact back-mount instrument is required. The 1/8 inch NPT back mount connection threads directly into standard fittings and manifolds, keeping the gauge profile tight against the panel or piping assembly. It is commonly installed on pressure test ports, service valves, and branch line taps across a range of system types.

Key Features

• 0-160 psi measurement range for low-to-moderate pressure monitoring
• 1/8 inch back mount connection for flush, compact installation
• Dry gauge construction with no fill fluid for clean, low-maintenance service
• Clear dial face for easy pressure reading in the field
• Compact form factor suitable for tight panel and piping installations

Compatibility

Designed as an OEM-style replacement or direct-install pressure gauge for plumbing, HVAC, and compressed air systems using standard 1/8 inch NPT back-mount gauge ports.

Installation Notes

Installation should be performed by a licensed plumber, pipefitter, or HVAC technician in accordance with applicable local codes and the IPC or IFGC as relevant to the system type. Depressurize and isolate the system before removing any existing gauge or fitting. Use an appropriate thread sealant on the NPT connection and hand-tighten before applying tool torque to avoid cracking the gauge housing. Do not exceed the rated 160 psi maximum working pressure.
